What do you consider a good HU? I went shopping the other day, they all have the same features but the price range from P10k to P30k. Nakita ko puro Alpine, Kenwood, JVC, and Pioneer.

They're all 50wX4, mp3 capable, USB, CD. Isn't P10k good enough to allocate para sa HU as long as good brands ang piliin tulad ng Alpine, Kenwood, JVC, and Pioneer? Hindi ba sa speakers at sub ang magdedetermine ng sound quality? I think the higher end P30k HU will have features like 7 band graphic equalizer, DSP chip and other gizmos that will allow you to manipulate the sounds. It's very complicated trying to learn these things.
